Combination of Echocardiography and Pulse Wave Velocity Provides Clues for the Differentiation between White Coat Hypertension and Hypertension in Postmenopausal Women

Association between Preeclampsia and Long-term Risk of Arrhythmias

BACKGROUND

Preeclampsia (PE), a pregnancy-induced hypertensive disorder, affects 4-5% of pregnancies worldwide. It is well known that hypertension is associated with an increased risk of arrhythmias; however, data on the association between PE and arrhythmias are sparse.

METHODS

In this observational cohort study, we identified all primiparous women who gave birth in Denmark (1997-2016) using Danish nationwide registries. The women were stratified on whether they developed PE during primiparous pregnancy, and followed from primiparous pregnancy to incident arrhythmia, emigration, death, or end of study (December 31, 2018).

RESULTS

A total of 523,271 primiparous women with a median age of 28 years were included and 23,367 (4.5%) were diagnosed with PE. During a median follow-up of 10.1 years, women with vs without PE were associated with a higher incidence of arrhythmias (1.42% vs 1.02%): 1) Composite of cardiac arrest, ventricular tachycardia/fibrillation, or ICD implantation (adjusted HR 1.60 [95% CI 1.14-2.24]), 2) Composite of advanced 2nd degree or 3rd degree atrioventricular block, sinoatrial dysfunction, or pacemaker implantation (adjusted HR 1.48 [95% CI 0.97-2.23]), 3) Composite of supraventricular tachyarrhythmias or extra systoles (adjusted HR 1.34 [95% CI 1.19-1.51]), 4) Composite of all the above-mentioned arrhythmias (adjusted HR 1.37 [95% CI 1.23-1.54]).

CONCLUSION

Preeclamptic women were associated with a significantly and at hitherto unknown long-term increased rate of arrhythmias. This finding suggests that women with PE may benefit from cardiovascular risk assessment, screening, and preventive education.

Safety and tolerability of intramuscular and sublingual ketamine for psychiatric treatment in the Roots To Thrive ketamine-assisted therapy program: a retrospective chart review

Background

In the last few years, ketamine is becoming increasingly common in the treatment of mental health conditions, but there is a lack of safety data informing intramuscular and sublingual dosing in a community-focused group psychotherapy setting. The Roots To Thrive ketamine-assisted therapy (RTT-KaT) program is a unique 12-week RTT-KaT program with 12 community of practice (a form of group therapy) sessions and three ketamine medicine sessions.

Objectives

This study reports on adverse effects of intramuscular and sublingual ketamine dosing in a community group psychotherapy setting among 128 participants across four cohorts.

Design

Retrospective chart review.

Methods

A chart review of the RTT-KaT Program was performed retrospectively on four cohorts (n = 128) that participated in 448 sessions running between September 2020 and December 2021. Baseline characteristics and adverse events were captured including medication administration before, during, and after RTT-KaT sessions. Analyses by session and by individual were conducted. Chi-square test with Yates' continuity correction was used to assess side effects in subgroups from ketamine administration.

Results

RTT-KaT was well tolerated with none of the 128 participants dropping out of the program. Primarily, of the 448 sessions, 49.16% had elevated blood pressures post-KaT session by session. In terms of other adverse effects, 12.05% of participant-sessions experienced nausea, 2.52% had an episode of vomiting, 3.35% had a headache, and seven participant-sessions experienced dizziness. Analysis by individual revealed congruent findings.

Conclusion

These findings suggest good safety and tolerability for RTT-KaT among individuals seeking treatment for mental health issues. The majority of participants did not experience adverse reactions and the adverse events that were recorded involved transient symptoms that were resolved with rest and/or medications. The group therapy model described provides a comprehensive approach and presents a promising model for operating a KaT program in a community setting.

Effects of white-coat, masked and sustained hypertension on coronary artery stenosis and cardiac arrhythmia

This study aimed to investigate whether hypertension phenotypes such as white-coat hypertension (WCHT), diagnosed with the addition of nighttime blood pressure (BP) criteria, are related to coronary artery stenosis (CAS) and cardiac arrhythmia. In this cross-sectional observational study, 844 participants who did not use antihypertensive, lipid-lowering, and antiplatelet drugs were selected. The subjects were divided into normotensive (NT), WCHT, masked hypertension (MHT), and sustained hypertension (SHT) groups based on the results of clinic BP measurement and ambulatory BP monitoring. Coronary angiography and ambulatory electrocardiography were performed to determine the participants' CAS and cardiac arrhythmia status. Coronary angiography revealed 556 patients with CAS and 288 participants with normal coronary arteries. The chi-squared test showed that the incidence of CAS was higher in the MHT and SHT groups than in the NT group, while no significant change was found in the WCHT group (P = 0.003, P < 0.001, P = 0.119). The logarithm of the Gensini score was used to compare the degree of CAS between the groups. Multiple linear regression analysis showed that the degree of CAS was higher in the WCHT, MHT, and SHT groups than in the NT group (P < 0.05). The incidences of frequent atrial premature beats, atrial tachycardia, and ventricular cardiac arrhythmia were significantly higher in the WCHT and SHT groups than in the NT group, while only ventricular cardiac arrhythmia changes were observed in the MHT group. This study found that hypertension phenotypes such as WCHT were closely associated with CAS and cardiac arrhythmia.

Decline of Renal Function and Progression of Left Ventricular Hypertrophy Are Independently Determined in Chronic Kidney Disease Stages 3-5

Invasive and noninvasive methods for evaluating the effects of hemodynamics on progression of left ventricular hypertrophy (LVH) in patients with chronic kidney disease (CKD) have been proposed. Central aortic pressure (CAP) has been reported to be the best among selected measures of hemodynamics for predicting LVH. However, there are few studies examining the relation between longitudinal changes in CAP and renal dysfunction in patients with CKD.

METHODS

Sixty-seven patients with CKD stages 3-5 (female/male ratio: 26/41, age: 61.5 ± 13.1 years) were followed for 5 years. Before and at the end of the 5-year period, CAP was recorded by an automated tonometric system (HEM-9000 AI; Omron Healthcare, Kyoto, Japan). Second systolic aortic blood pressure (SBP2) was employed as an index of CAP.

RESULTS

Throughout the study, systolic blood pressure (SBP) was well controlled. Renal function followed by estimated glomerular filtration rate (eGFR) gradually worsened as a whole. Ten patients had renal replacement therapy, 3 patients developed cardiovascular diseases and 2 patients were found to have a neoplasm during the 5-year observation period. SBP2 increased from 120 ± 19 to 125 ± 33 mm Hg and eGFR decreased from 38.2 ± 18.2 to 29.5 ± 16.3 ml/min/1.73 m(2); however, these differences did not achieve significance. The left ventricular mass (LVM) index significantly increased from 115.5 ± 10.5 to 131.2 ± 11.7 g/m(2) (p < 0.05). Although the changes in SBP2 and eGFR looked like a mirror image, there was no significant correlation between the two factors. Moreover, multivariate regression analysis did not reveal a close correlation between SBP2 and CKD progression. In contrast to the decline of renal function, the baseline value of SBP2 predicted an increase in the LVM index.

CONCLUSION

Worsening of renal dysfunction is not solely dependent on hemodynamics. Other factors might be involved in a complex manner.
